	=head1 Bubble sheet grading routines

	For this documentation:

	'scanline' refers to the full line of characters
	from the file that we are parsing that represents one entire sheet

	'bubble line' refers to the data
	representing the line of bubbles that are on the physical bubble sheet


	The overall process is that a scanned in bubble sheet data is uploaded
	into a course. When a user wants to grade, they select a
	sequence/folder of resources, a file of bubble sheet info, and pick
	one of the predefined configurations for what each scanline looks
	like.

	Next each scanline is checked for any errors of either 'missing
	bubbles' (it's an error because it may have been mis-scanned
	because too light bubbling), 'double bubble' (each bubble line should
	have no more that one letter picked), invalid or duplicated CODE,
	invalid student ID

	If the CODE option is used that determines the randomization of the
	homework problems, either way the student ID is looked up into a
	username:domain.

	During the validation phase the instructor can choose to skip scanlines.

	After the validation phase, there are now 3 bubble sheet files

	scantron_original_filename (unmodified original file)
	scantron_corrected_filename (file where the corrected information has replaced the original information)
	scantron_skipped_filename (contains the exact text of scanlines that where skipped)

	Also there is a separate hash nohist_scantrondata that contains extra
	correction information that isn't representable in the bubble sheet
	file (see &scantron_getfile() for more information)

	After all scanlines are either valid, marked as valid or skipped, then
	foreach line foreach problem in the picked sequence, an ssi request is
	made that simulates a user submitting their selected letter(s) against
	the homework problem.
